Waste battery should be handled properly in line with relevant laws and
regulations.

6.4 Troubleshooting

There are lots of reasons for the troubles, besides production quality or transportation
and storage, unsuitable maintenance will lead to many troubles. After the failure launch, it's
necessary to analyze and take effective measures to remedy as soon as possible. The
features, reasons and troubleshooting of the common troubles are as follow:
Feature
1. Rated capacity not being
reached or not enough.
Capacity drops
2. Capacity drops gradually.
3. Capacity drops suddenly.
1. The voltage is too high
when charging, drops quickly
Voltage is
when discharging.
abnormal
2. Opening voltage reduces
markedly.
Cause
Not enough charge.
Density of electrolyte is too
low.
The connecting line isn't
clear, too high resistance.
Pole plates are sulphated
There is harmful matter in
electrolyte.
The battery is localized
short circuit.
The inner or outer short
circuit of battery
The pole plates are
sulphated
Opposite pole, short circuit.

Remedy
Balanced charging,
improve the operating
way.
Adjust the density of
electrolyte.
Unblock the outer
connection line and
reduce the resistance.
Charging repeatedly to
exhaust the condition of
sulphating.
Check electrolyte,
replace it if necessary.
Check and remove.
Check and remove.
Exhaust the condition of
sulphating.
Check signal voltage and
exhaust it.
